How to process and store medicinal centipedes?

(1) Harvesting method When centipedes grow to more than 10 cm, they can be harvested and processed for medicinal purposes. The harvesting time is generally from July to August each year, and the main purpose is to harvest excess males and old females, leaving healthy females to breed. Centipedes have a pair of venomous fangs, and they often bite people with their venomous fangs when they are captured. Therefore, tools must be prepared when harvesting. Usually, bamboo chopsticks and tweezers are used as harvesting tools, and smooth plastic buckets, large-mouthed bottles or cloth bags are used as storage containers. When harvesting, first remove the tiles, and after finding the centipede, use chopsticks or tweezers to clamp it and put it in the storage container. Experienced people can catch it with their bare hands: first press down its head with the index finger or other tools, and then throw it into the storage container after catching it. When throwing it, be careful to take the head and tail out of your hand at the same time to prevent being bitten by the centipede.

(2) Sun-drying: First, place the captured live centipedes in a pot and scald them to death with boiling water. Be careful not to scald them. Then cut off the tail end and squeeze out the feces and urine. Then, take a thin bamboo piece with the same length and width as the centipede, sharpen both ends, insert one end under the centipede's jaw and the other end into the tail. Use the elasticity of the bamboo piece to straighten the centipede and place it in the sun to dry. During breeding, if you encounter centipedes that have died but have not deteriorated, you can pick them out and expose them to the sun in time to prevent them from deteriorating and losing their medicinal properties.

(3) Drying If it is rainy, use charcoal fire or microwave oven to dry. After drying, remove the bamboo strips. Be careful not to break the head and tail, which will affect the quality. Place centipedes of similar length with their heads facing one side, clamp them horizontally at the back and abdomen with a thin bamboo strip about 1 cm wide, tie them into rows, 50 per row, and seal them in wooden boxes for storage.

(4) You can also scald the centipedes to death and then stretch them straight without using bamboo strips. Pin them to cardboard with pins and place them in the sun to dry. Then tie them together in groups of 100 and wrap them in plastic wrap to prevent moths.

Is it true that Tianlong centipede farming in Zaoyang is successful?

The breeding of Tianlong centipede in Zaoyang is real and successful.

Feeding techniques

1. Like to live in groups: Centipedes have the habit of living together, big and small. Centipedes in the same group can live in harmony and rarely fight and kill each other. If the habitat is too small and there are too many centipedes, the old centipedes will automatically leave and find another habitat.

2. Centipedes are timid and easily frightened. If they are slightly frightened, they will stop eating, flee from their nests, or curl up motionless. Female centipedes that are laying eggs will immediately stop laying eggs, while centipedes that are incubating eggs will, contrary to their normal behavior, eat the eggs if frightened.

3. They like dark and humid places. Wild centipedes mostly live on hillsides, fields, roadsides, weedy places, or in firewood piles and gaps between roof tiles. They also often live in dark corners such as kitchen corners. Centipede footprints are also often seen under the bricks and tiles around pig pens and chicken coops.

4. They live in their nests during the day and come out at night. The peak of centipede activity is from 8 to 12 p.m., and they usually return to their nests to rest before 4 a.m. It is difficult to see centipedes after daybreak.

During the day, the centipede has poor eyesight and cannot see clearly things that are a little far away, so it is difficult for it to find food and defend against enemies. It only uses a pair of slender tentacles extending forward to explore the way, and at night it also uses its tentacles to search for prey for food.

5. Licking habits

Centipedes frequently lick their antennae and legs with the dense hairs on the protrusions of the first maxilla and the base of the maxilla, the brush-like bristles on the back of the second maxilla, and the saliva from their mouths. They also lick their own nests to keep them clean.

6. Temperature Centipedes are temperature-changing animals, and all their activities are often related to temperature. The most suitable temperature for centipedes to grow and develop is 25℃～32℃. When the temperature is 11℃～15℃, centipedes will reduce their foraging, stop mating and lay eggs. When the temperature drops below 10℃, centipedes will stop all activities, drill into the loose soil (or nest soil), curl up and hibernate. However, when the temperature rises to 33℃～35℃, all its activities will be suspended due to the loss of water in the body. If the temperature rises above 36℃, the body will lose too much water, causing the body to dry up and die.

7. Humidity: When the relative humidity of the air in the breeding room is 60% to 70% and the humidity of the nest soil is 10% to 20%, all the life activities of the centipede are most active. In other words, this is the most suitable humidity for the growth and development of the centipede.

Preparation of breeding soil:

When breeding centipedes artificially, breeding soil is indispensable for their lives, because breeding soil can provide a comfortable home for centipedes, which can keep them warm in winter and provide them with shelter from the heat in summer. At the same time, centipedes can also absorb water and nutrients from the breeding soil. Centipedes have strong adaptability to breeding soil, and both sandy soil and loam are fine, but the breeding soil must be loose, fertile and moist, so it is best to use garden soil as breeding soil. It is not suitable to use clay as breeding soil, because clay is easy to compact and centipedes find it difficult to enter. Before compaction, due to its high viscosity, it will also stick to the centipede's feet and mouthparts, affecting the centipede's crawling and feeding activities. First, dig garden soil from a place that is not contaminated by pesticides and fertilizers, then crush it, and remove impurities, stones, tiles, etc. from the soil, then expose it to sunlight for disinfection, kill insects and eggs such as ants and mites in the soil, as well as bacteria and mold, to reduce centipede diseases and pests, and set it aside after drying.

1. Centipede breeding pond

Centipedes have strong climbing ability but cannot swim. Based on this characteristic, we have developed a new centipede breeding and management technology, which can be designed as follows:

Water-surrounded centipede breeding pond, glass inner eaves centipede breeding pond, etc.

2. Food and Beverages

Centipedes are typical carnivorous animals. They like all kinds of living insects, such as crickets, locusts, mealworms, dragonflies, cockroaches, flies, bees, and the pupae and eggs of these insects. They also eat spiders, earthworms, snails, geckos, snakes, frogs, birds, mice, etc. When they are hungry, they also eat a small amount of young leaves and buds of plants.

3. Management:

When you catch centipedes from the wild for breeding, you can choose healthy and healthy ones. If the density of centipedes is too high, they are disturbed too much, or there is insufficient feed and water, they will kill each other. For piles of tiles and stones, 300 centipedes can be released per square meter based on the bottom surface area.

Isolate the pregnant female centipede:

Centipedes are dioecious. The female centipede that is about to lay eggs is bloated, with her abdomen almost touching the ground, and moves slowly, making it easier to identify. Centipedes are best kept in isolation during the egg-laying and hatching period. The method is to place a small basin in the breeding basin or use a canning bottle to keep them separately to avoid interference from other centipedes and facilitate management.

Heating method of feeding room

The breeding room must be well built and equipped with conditions for heating, temperature control and good thermal insulation. Generally, the size of such a breeding room depends on the number of centipedes that will overwinter, the heating conditions and whether the heat supply is sufficient. There are many ways to heat. You can use coal stoves, wood chip stoves, rice husk stoves, electric heating pipes, etc.

Harvesting and processing of centipede products

They are usually caught between April and June. After catching them, sharpened bamboo sticks are inserted into their heads and tails. Then they are stretched out in the sun or scalded with boiling water until they are dried. In some areas, chicken feathers and bones are buried in damp places in winter to lure centipedes to lay eggs and reproduce. They are then caught in the beginning of spring.

Centipede breeding density: Centipedes like to live in groups. The breeding density of centipedes should be different according to the solar terms, insect shape, thickness of sand and temperature. When the temperature is low and the sand is thick, the breeding density can be higher. On the contrary, when the temperature is high and the sand is thin, the density should be sparse. It is appropriate to breed about 6,500 young centipedes per square meter after leaving the delivery room, about 3,500 for 5 cm, 2,000 for 7-10 cm, 1,100 for 12 cm to 13 cm, and 600 for more than 15 cm.

Centipede requirements for pond soil

Summer is humid, spring, autumn and winter are dry, and the relative humidity of the environment around the breeding basin should be maintained at about 70%. If the soil in the basin is too wet, you should consider replacing it or sprinkling some dry soil in the basin to absorb moisture. Some people mistakenly add fertilizers such as cow dung and some chicken bones to the soil layer in the basin to feed centipedes with insects, which is detrimental to the environmental hygiene of the pond and easily causes pollution.

Centipede feeding and management:

1. Maintain a quiet environment: Centipedes require a quiet environment for egg laying and hatching. If disturbed, they often eat eggs and larvae. Generally, females lay eggs at different times in the same breeding pond. Females that have not laid eggs often interfere with the normal egg laying and hatching, and some even eat eggs. Therefore, before females lay eggs, they should be raised separately, or isolated in a large breeding pond with glass sheets, bottomless glass cups or cans.

2. Enhance feeding before laying: Centipedes do not eat or drink water during the incubation period, and rely on consuming their own nutrients to maintain activities. Before laying eggs, the female has the habit of eating a lot to accumulate nutrients. At this time, the feeding amount should be increased, and attention should be paid to adjusting the food types to encourage the female to eat more and increase nutrition before hatching.

3. Management during the incubation period: During the period of centipedes incubating eggs and raising their young, they will react to disturbance, vibration, strong light, strong sound, etc. Therefore, the breeding room must be a quiet and dark place. It is best to install a red light indoors and cover the windows with cloth or bamboo curtains to prevent strong light exposure. The incubation tank in the room should be placed in advance, and once the eggs are laid, do not move them easily. Do not move the protective glass sheet (pressed sheet) casually, and do not use a flashlight to illuminate it. If the humidity in the incubation nest is too low, it will affect the normal development of the embryo, so water should be added to the incubation tank in time. When adding water, it should be poured slowly along the wall of the tank so that the inner wall around the incubation nest is slightly damp. When the incubation is over, because centipedes compete for food and the big ones eat the small ones, the females should be removed in time or the young ones should be raised in different nests.

Sweat, any choice is better than that one. The five families we introduced together are from Suizhou, Huang Gang, and Hunan. I am from Zaoyang. All five of us died. Brother, I feel so depressed. Be careful.

I don't know where you are talking about. But there are people who breed centipedes. It can be successful. But the commercial value is mainly for medicinal use.
